I saw this in their placement report with data from September:
Change in their job sector 72%
Change in their job function 71%
Change in their job location 48%

That means that the average participant made two of those three changes. Pretty impressive! It's at http://www.google.co.uk/url?sa=t&rct=j&q=hec%20placement%20report%20mba&source=web&cd=3&cad=rja&ved=0CEEQFjAC&url=http%3A%2F%2Fwww.mba.hec.edu%2Fcontent%2Fdownload%2F1700%2F10383%2Fversion%2F1%2Ffile%2FPlacement%2Breport%2B2012.pdf&ei=61JdUY_XHYbmOtC-gaAI&usg=AFQjCNEp_BxDVFPuCIIcer4eR-HDxwiP7Q&bvm=bv.44770516,d.ZWU

That is impressive. And the FT ranks it very highly, in terms of international mobility (although it's outperformed by both LBS and IMD.)

For international students wanting to work in Euroep, HEC definitely gives Insead a run for its money - if post-graduation salaries were a bit better, I'm sure it would rise in the rankings.
